The fuzzball proposal states that associated with a black hole of entropy S, there are
expShorizon-free non-singular solutions that asymptotically look like the black hole but …

We review the recent progress towards applying worldsheet integrability techniques to the
${\rm Ad}{{{\rm S}} _ {3}}/{\rm CF}{{{\rm T}} _ {2}} $ correspondence to find its all-loop S matrix …

We construct a conformal field theory dual to string theory on AdS 3 with pure NS–NS flux. It
is given by a symmetric orbifold of a linear dilaton theory deformed by a marginal operator …

We discuss in detail the 1+ 1-dimensional superconformal field theory dual to type II string
theory on AdS 3× S 3× T 4, emphasizing the string theoretic aspects of this duality. For one …

A bstract In this note we prove a non-renormalization theorem for the 3-point functions of 1/2
BPS primaries in the four-dimensional\(\mathcal {N}= 4\) SYM and chiral primaries in two …

A bstract We revisit the computation of string worldsheet correlators on Euclidean AdS 3 with
pure NS-NS background. We compute correlation functions with insertions of spectrally …

A bstract We explore the stringy structure of 1/2-BPS bound states of NS fivebranes carrying
momentum or fundamental string charge, in the decoupling limits leading to little string …

A bstract We compute a large collection of string worldsheet correlators describing light
probes interacting with heavy black hole microstates. The heavy states consist of NS5 …

We develop a diagrammatic language for symmetric product orbifolds of two-dimensional
conformal field theories. Correlation functions of twist operators are written as sums of …

The fuzzball proposal says that the information of the black hole state is distributed
throughout the interior of the horizon in a'quantum fuzz'. There are special microstates where …
